Question

Suppose we put a medium in front of charge we know the electric field intensity will decrease upto relative permitivity of that medium.

But the question is that if we increase the mass of same medium then the electric field intensity will decrease more or will remain assisitive?

If electric field intensity changes by increasing the density of medium,then relative permitivity of that same medium will also change. But it doesn't.​

Answer 1

Answer:

Explanation:

In general capacitance of parallel plate capacitor is given by:  

C=  

d

kϵ  

0

​  

A

​  

 

where C is capacitance, k is relative permittivity of dielectric material, ϵ  

0

​  

 is permittivity of free space constant, A is area of plates and d is distance between them.  

Therefore, the capacitance of parallel plates is increased by the insertion of a dielectric material.  Further, the capacitance is inversely proportional to the electric field between the plates, and hence the presence of the dielectric decreases the effective electric field.
